AARON P. GOULD, OF NORTHWILKESBORO, NORTH CAROLINA, ASSIGNOR T VJ. C. MEADOWS MILL 00., 0F NORTHWILKESBORO, NORTH CAROLINA.

AGITATOR.

Application filed August 27, 1920. Serial No. 406,373.

To all whom it may concern Be it known that I, AARON P. GOULD,

a citizen of the United States, residing at Northwilkesboro, in the county of Wilkes 6 and State of North Carolina, have inventeda new and useful Agitator, of which the following is a specification.

The present invention relates to grinding mills, for grinding flour, meal or the like, and it is the primary object of the in vention to provide a novel agitating means to insure the true operation of the feed pan, which is supported directly under the feeding hopper.. V

A further object of the invention is the provision of a'cam engaging element to be pivotally secured to an agitating lever and arm, the mechanism being simple in construction, using a minimum amount of power in the operation thereof, the mechanism being of a form to automatically take up wear between the elements, thereby eliminating lost motion and providing an absolutely noiseless structure.

With the foregoing and'other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings I Figure 1 illustrates a perspective view of a mill, showing the invention as applied thereto, portions of the mill being broken away. V

Figure 2 illustrates a fragmental side elevational View disclosing the agitating means; and

Figure 3 illustrates a longitudinal sectional View through the agitating means, and a portion of the mill.

Having reference to the drawings in detail, the reference character 5 designates'a mill, which is of the usual construction, and includes a base 6 on which the mill is supported, which base also supports the bearing members 7 and 8 that support the power shaft 9, which operates the grinding mechanism of the mill, which is not shown in the present drawings.

Supported on the power shaft 9 is the usual pulley 10, which has connection with power means to cause the rotation of the shaft, and on this shaft 9 is supported the disk 11, which is disposed at an angle with relation to the horizontally disposed power shaft 9 for purposes to be hereinafter more fully described. 1

The bearing 12 which supports the power shaft 9 is provided with an arm 13 extending upwardly therefrom, the arm being provided with a boss let adapted to form a seat for the coiled spring 15, one end of the coiled spring 15 being however, seated over the boss 16 of the collar 17, so that the spring 15 is maintained in operative relation with the bearing 12 and operating arm 18.

The operating arm 18 has pivotal connection with the frame of the mill, by means of the bracket 19 which is bolted to the mill frame, the bolt 20 which connects the opposed arms 21 of the bracket, forming the pivot pin for the arm 18, to permit the arm to rock with relation to the power shaft 9.

Connected to the operating arm 18 by means of the bolts 22, is the agitating bar 23, which as shown by Figure 1 of the drawings has connection with the feed pan 24: to agitate the same. The collar 17 is supported on one end. of the operating rod 18 and is provided with an oil reservoir, 38, a lubricating tube 25 which supports the shafts 26 in one end thereof, which shaft accommodates the wheel 27 and provides a means for keeping the wheel 27 lubricated.

It will thus be seen that the wheel 27 is supported in contact with the disk 11, so that rotary movement of the disk 11 is imparted to the wheel 27 to cause the operating of the arm 18.

A threaded opening 28 is formed in the outer surface of the collar 17 and receives the threaded extension of the bolt 29, which has a washer 30 supported thereon that forms an abutment for one end of the coiled spring 31, the opposite end of said coiled spring contacting with the seat 32 which contacts with the movable arm 33 that is forked to embrace a portion of the bolt 29.

This spring always keeps the washer 32 pressed against the fork which in turn presses against the oval part of the collar 17 insuring against rattling. Nut on said rod allows the spring to be adjusted should the spring become inefficient.

This arm 33 is formed so that the relatively flat surfaces thereof will lie parallel with the bar 34 to receive the pivot pin 35 disposed in spaced relation with one end or the arm 33 to permit the arm to pivot in a horizontal plane to operate the bolter 36 which has connection with ,.tl1e arm 33 through the medium of thebolt 37. From the foregoing'it is obvious that rotary movement of the power shaft 9, imparts rotary movement to the disk. 11, which as before stated transmits motion to the wheel 27 to cause the arm 18 to reciprocate the feed pan 24:, and that movement ofthe arm 18 also transmits reciprocatory movement to the bolter 36, through the pivoted arm 33, the coiled spring 31 however compensates for the movement of the arm 33 with relation to the bolt 29, and maintains the arm 33 into 'close engagement with the collar 17 to insure the efficient operation of the device.

It might be further stated however that in the upper end 'of the tube 25 is positioned an oil cup 38 which supplies the shaft '26 and its wheel, with 'a lubricant. In

It is believed that in view of the foregoing disclosure, further detail description of the operation of the agitating device step by step, is unnecessary.

Having thus described the invention, what is claimed as new is In a device of the character described, a

support, a bearing forming a part of the a lower end disposed adjacent to the disk, a

collar on one end of the arm, and carrying a boss, a coiled spring positioned between theboss of the collar and the boss formed on the arm of the bearing, a wheelmounted at the lower end of the arm and adapted to engage the disk, to impart movement from the disk to the arm, an arm bearing against thecollar, and a coiled spring for holding the last mentioned arm into engagement with the collar whereby reciprocating movement of the'collar and arm supporting the collar will result in a relative movement of the last mentioned arm. 7

as my own, I have hereto aiiixed my =signa-
